Threshers

Threshers are large worm-like creatures that come in many shapes and sizes. They live in many different environments around Pandora. While one person may be fighting a Thresher's head in one place, a team-mate may be fighting the same Thresher's tentacles somewhere else.

The Wormhole Thresher is completely covered in spikes, and has the ability to create a wormhole that draws you in, and impales you if you get too close to it doing damage over time as long as the wormhole holds you next to the thresher..
